Well you can clear the screen.
Try with
Console.Clear();
method.
UPDATE:
after seeing other peoples replay maybe I got a question wrong.
Check this example:
class Program
{
static void Main(string[] args)
{
Console.Clear();
bool done = false;
while (!done)
{
ShowMenu();
ConsoleKeyInfo keyHit = Console.ReadKey(true);
Console.Clear();
switch (keyHit.KeyChar)
{
case '1':
SimpleArraySort();
break;
case '2':
SimpleListSort();
break;
case '5':
PerformanceTest();
break;
case '9':
done = true;
break;
default:
Console.WriteLine("Please enter a valid option. \r\n");
continue;
}
}
}
}
Cheers
